Fluid Systems

Summary

Fluid systems are commonly used in many control systems

Governing Principles

• Continuity $m^{\prime }=w_{in}-w_{out}$ similar to how its used in Mass and Energy for Open System
• Flow rate is determined by $w=\frac{1}{R}{\left(P_1-P_2\right)}^{\frac{1}{2}}$
• Force equilibrium is governed by Newtons 2nd Law
• You may need to use the mass flow rate equation from Mass and Energy for Open System typically $m^{\prime }=\rho A{h}^{\prime }$ where $A$ and $h$ are just used to get volume
